514 ACUS02 KWNS 221634 SWODY2 SPC AC 221632 Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1132 AM CDT Fri Aug 22 2025 Valid 231200Z - 241200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... The potential for severe storms is low across the continental U.S. for Saturday. ...Synopsis... An upper trough will deepen over the Great Lakes and Midwest, enveloping much of the eastern half of the U.S. on Saturday. Meanwhile, an amplified upper ridge will persist across the West. At the surface, a cold front will extend from Upper MI into northeast NM Saturday morning, and sweep east/southeast through the period across much of the MS/OH Valleys into the southern Plains. A seasonally moist airmass ahead of the front will result in a narrow corridor of modest destabilization across Lower MI into the Mid-MS Valley, and westward across parts of KS/OK and the central/southern High Plains. Isolated to widely scattered thunderstorms may develop near the cold front, or in the post-frontal upslope regime across the central High Plains. Modest midlevel lapse rates are forecast amid MLCAPE around 1000 J/kg. Poor convergence along the front and weak large-scale ascent with south and westward extent should limit storm coverage. Overall, severe potential appears low. ..Leitman.. 08/22/2025 $$
